SPECIFICATION forming part of LettersI Patent No. 316,008, dated April 21, 1885. Application tilccIOctober 20, 1853. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM T. CARROLL,

a citizen of the United States residing at Worcester, in the county of `Worceste`riand 5 State of Massachusetts, have invented certain new and useful Improvements in Spinning and Twisting Machines; and I declare'thev following to be a description of my said linvention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

which form a part of this specification. The objects of my present invention are to provide a spinning or twisting machine having band-cylinders which are formed in four or more independentsections, arranged in the manner described, and having auxiliary thereto a main operating-shaft with suitable gearing, clutch, and shipping mechanism for independently connecting and actuating the said cylinder-sections, whereby a more convenient and desirable mechanism is produced. These objects I attain by mechanism the nature, construction, and operation of which are explained in the following description, the particular subject-matter claimed being hereinafter definitely specified. i

In the drawings, Figure lis a front view. Fig. 2 is a horizontal section above the cylin-v ders and operating-shaft; and Fig. 3 is avertical section at a position centrally between' the supporting-frames, the said gures severally showing such parts of a spinning or twisting machine as will illustrate the nature of my invention. Fig. 4 is a longitudinal sectional view of the clutch devices on the cylinder-shafts. Fig. 5 is a transverse section at line x x, Fig. 4. Fig. 6 is a transverse section at line y y, Fig. 4, showing details of the clutch. Fig. 7 is a plan view showing a modification in arrangement of the clutches and gears, and Fig. 8 is an elevation diagram indicating the modified arrangement of the gears, as hereinafter referred to.

In the present drawings the machine is, to economize space, shortened in length, the connections and end portions of the cylinder-sections being shown. It will, however, be un- 5c derstood that the machine may be made of any required length to accommodate any desired number of spindles. The parts of the machine which are not herein shown and specified maybe constructed and arranged for operation in 'the ordinary or any suitable well- 55 known manner.

In referring to parts, A designates the frame, which may be of any suitable form for properly supporting the operative parts.

" B B denote the bolster-rails, S the spindles, and b the spindle-bands.

1 C C indicate the band-cylinders from which the spindles are operated. Said cylinders are made in separate sections, (respectively nurnbered l 2 8 4,) and each section is mounted 1n 65 bearings@ for action independent of the other sections. n

D designates an operating-shaft extending throughout the length of the machine, parallel with the cylinders C C, and mounted to turn in bearings d d on frame A, the position of the shaft D being in this instancecentrally between andslightly above the cylinders, so that the cylinders at either side are geared to and operated therefrom in a uniform manner, said shaft Dbeing provided with a pulley, E, (or tight and loose pulleys) for the drivingbelt, and the entire mechanismv being operated by the single belt on said pulley E, the motion being transmitted to the several different 8o sections `ofthe machine by means of the shaft D and connecting gearing.

The-respective shafts C of the cylinder-sections C are provided with gears F, that mesh with gears G on the operating-shaft D, as shown, by means of which motion is transmitted to the said cylinders. The gears F are mounted loose on the cylinder-shafts, the latter being provided with a frictionclutch mechanism, I, whereby the parts canbe put into and out of action by suitable shipper mechanism. The clutches are in the present instance made as shown in detail in Figs. 4, 5, and 6. The gear F is provided with a hub,

F', having a friction-surface, which is sur- 9 5 rounded by a band or ring, I, that is open at one side and arranged to spring away from the friction contact with the hub. This ring is inclosed in a suitable casing, J, and retained bylugsj, so that it cannot turn out of place in ico relation to said case J. The case is rigidly fixed to the cylinder-shaft C.

A rocker bar or cam, K, is arranged in connection with the case J, one side of which bar is flattened and fitted to engage with one of the lugs j, formed on the ring I', as illustrated in Fig. 6. or cam acts upon the lug for closing the ring I onto the surface of the hub and setting the friction so that the gear F and case J will revolve together. Said rocker is provided with an arm, K', that engages the conical shippersleeve L, which is moved back and forth on the shaft C', for throwing the clutch into and out of action by means of the forked lever m and shipper-rod M, arranged at a convenient position along the front of the machine.'v

In the instance just described the clutch mechanism I is located upon the cylindershafts C, but, if desired, it might in some cases be arranged upon the shaft D, as hereinafter described, separate gears G being used for the separate cylinders, as illustrated in Figs. 7 and 8, on which figures the shafts, gears, clutches, and cylinders are indicated by the same reference-letters as on the other views, so that their modified relation will be readily understood by any person skilled in this class of machinery. 'Ihe machine as here shown comprises four independently operative sections; but I do not Wish to confine myself to that particular number, as it is evident that the machine may` b e made to comprise any desired number ofsections by arranging the clutches intermediate between the ends of cylinder-sections and extending the shaft D and frameA to the necessary dimension for supporting and actuating the several divisions. Again, if desired, one side of the machine may be made to comprise long sections and the other side short sections as, for instance, two sections on one side and three or four sections on the other side-each section being arranged to be independently actuated from the central operatingshaft, D, in the manner set forth.

The arrangement of gears for transmitting motion to the feed-rolls is indicated in the drawings. The `rolls for each section take their motion from the cylinder-shafts C' of that section by the gears e f, stud n, and gears o p r, which latter are mounted in the usual manner on suitable studs fixed to the end frames of the respective sections, (see Fig. 2 and dotted lines Fig. 3,) so that the spindles and feed-rolls in each section act in unison Vhen rocked or turned, said bar with the cylinders, and are stopped and started by the clutch I on the cylinder-shaft C.

By constructing the machine in accordance with my invention it is rendered more convenient and economical. In doiiing, or when tying up breaks in the yarn, only one sectionhas to be stopped; consequently a machine having a large total number of spindles can be used with economy, both with regard to cost of construction and cost of attendance and power, and with the additional advantage in the greater amount and variety of Work produced.

Another advantage attained by the use of 7o the auxiliary shaft D is, that the cylinders are relieved from a great amount of torsional strain, which, with the ordinarily-constructed machines, has heretofore been asource of frequent damage by twist-ing or breaking the cylinders, Which are composed of only a thin shell of tin-plate.

The clutch mechanism for the cylinders and the driving-belt pulleys could, if preferred, be located at a central position, instead of at the ends ofthe machine, in which case the shaft lsaid cylinder, and the clutch devices I, ar-

ranged for connecting the cylinders with and disconnecting them from the auxiliary driving-shaft, substantially as shown and described.

2. The combination of the cylinders C and spindles and drawing-rolls actuated therefrom, arranged in separatelyoperative sections, the auxiliary shaft D, the gears G and F, for transmitting motion from said shaft to said cylinder, the clutch mechanism I, arranged for connecting the cylinders with and disconnecting them from said auxiliary shaft, and the shipper devices m, constructed and arranged substantially as shown and described.

Witness my hand this 5th day of October, A. D. 1883.
